Abstract
The invention relates to a gas-water spraying device for continuous casting. The gas-water spraying device comprises an outer arc spraying pipe, an inner arc spraying pipe, a side arc spraying pipe I, a side arc spraying pipe II, nozzles, nozzle bases and water inlets, wherein the outer arc spraying pipe, the inner arc spraying pipe, the side arc spraying pipe I and the side arc spraying pipe II are symmetrically distributed around a workpiece; each spraying pipe is welded with the water inlet, a plurality of nozzle bases and nozzles, and is composed of a gas pipe and a water pipe; the water inlet is connected to each gas pipe; and each gas pipe and each water pipe are connected to each gas-water nozzle. The gas-water spraying device has the advantages that structure is small, and use is convenient; water atomization is good because the spraying pipes are symmetrically distributed and are divided into a plurality of sections for receptively controlling corresponding flows and angles of the nozzles; water drop diameter is small, and cooling is uniform; the diameter of the outlets of the nozzles is large, so the outlets of the nozzles are difficult to block; the quantity of nozzles is less, larger cast blank area can be evenly covered, and water is saved; and flow regulation range is large, and the impact force of wide-angle stream strands is high for achieving higher cooling effect and uniform degree of cast blanks. The gas-water spraying device is suitable for cooling all steel grades.
Description
Technical field
The present invention relates to a kind of strand spray cooling device, relate in particular to a kind of gas-water spraying device for continuous casting.
Background technology
Strand with the liquid heart out enters secondary cooling zone from crystallizer, and cooling water is sprayed directly on to and further cools off on the strand and finish the task of all solidifying.Therefore, slab quality and casting machine productivity are decided by the level of the distribution of secondary intensity of cooling, cooling water and control, the type of cooling, two cold-zone equipment to a great extent.
Secondary cooling is to leaving the cooling of spraying water of crystallizer band liquid heart strand, so that strand solidifies fully, and controls casting blank surface temperature and evenly descends in the throwing direction.
Be to adopt directly to spray water strand is cooled off in two cold-zones, all heat radiation has a direct impact the distance between intensity of cooling, cooling water inflow, hydraulic pressure, water temperature, nozzle arrangements and layout, nozzle and strand etc. to strand.Should require to determine reasonable cooling system according to steel grade and section.
The casting blank shell thickness that pulls out from crystallizer increases gradually in two cold-zones, and just having left crystallizer is that the base shell is thinner, and it is large that injection flow rate is wanted, so that the base shell thickens rapidly.Along with strand moves in two cold-zones, shell thickness increases, and injection flow rate should reduce gradually, and cooling length strengthens gradually.Therefore, two cold-zones are divided into some cooling sections, each cooling section carries out separately water yield control, and work-piece cools effect and quality are seemed to be even more important.
Summary of the invention
The present invention provides a kind of simple in structure, the air water atomizing effect is good, impulsive force is high gas-water spraying device for continuous casting in order to overcome the above problems.
Technical scheme of the present invention is: comprise outer arc shower, inner arc shower, side arc shower one, side arc shower two, nozzle, nozzle carrier and water inlet, described outer arc shower, inner arc shower, side arc shower one, side arc shower two are symmetrically distributed in around the workpiece, be welded with water inlet and some nozzle carriers, nozzle on the described every shower, described every shower is made of tracheae and water pipe, water inlet is connected on the tracheae, and described tracheae and water pipe are connected on the air-water nozzle.
The present invention is simple in structure, easy to use, and shower is symmetrical and be divided into some sections and can distinguish Control Nozzle and spray corresponding flow and angle, and water atomization is good, and drop diameter is little, and cooling evenly; The jet expansion diameter is large, is difficult for stopping up; Nozzle quantity is few, the strand area that uniform fold is larger, using water wisely; Flow adjustment range is large, the wide angle stream thigh of high impact forces, and to reach cooling effect and the uniformity coefficient very high to strand, the present invention is applicable to the cooling of all steel grades.
